Remarks: We would like to request a NICER observation on the same day as our optical observation (see below). If possible, we would like to ask to carry out the observation within the same period as the optical observation (i.e., UT 19:00-20:30 on Feb. 23), but an observation outside this period is acceptable.

Coordinate Observation: Y
Observatory: KYOTO UNIVERSITY 3.8M
Description: We are going to perform optical spectroscopy of MAXI J1820+070 in Feb 23 UT 19:00-20:30 using the 3.8m telescope. We have also requested a Swift/UVOT observation in the same period. NICER will enable us to obtain high quality X-ray data, which is important to determine the strength of the X-ray irradiation on the outer disk, by modelling multi-wavelength SED.
